I agree with the poster above, stealing medication that you need is abuse. Stealing our money is abuse. Making us think that we are the crazy ones is abuse. Using words that disappoint, instead of actions that truly show intention...is abuse.
Abuse is a deal breaker and these days I cut slack for no abuser. Mama may mean well but she is giving very bad advice. I think you know that.
Leaving the relationship will hurt....staying will hurt more.
I am so very sorry for your pain.
